Ferrea Subaru EJ20 37mm 5.97mm 104.6mm 19 Deg +1mm 6000 Series Int Valve - Single (D/S Only)

If you're rebuilding the top end of your Subaru EJ20 engine, you'll want to make sure you're using reliable components for the intake valves. This Ferrea 6000 Series intake valve is built for that purpose. It measures 37mm in diameter with a 5.97mm stem and a length of 104.6mm, featuring a 19-degree seat angle. This specific valve is designed to be 1mm oversized, which can be beneficial for engines that have been bored out or require a larger valve for improved airflow. Ferrea is known for using strong materials in their valve manufacturing, aiming for durability under demanding engine conditions.

The 6000 Series is Ferrea's line of valves made from high-quality stainless steel, chosen for its strength and resistance to heat. This particular valve is intended for the intake side only and is a single unit, often referred to as 'D/S Only' meaning Driver's Side, though it's crucial to confirm fitment for your specific application. When installing, ensure you're using appropriate valve guides and seals to match the valve's dimensions and stem size for optimal performance and longevity.
